Goldberg absolutely hated Rihanna's Super Bowl halftime show on Sunday ... calling the singer's performance "horrible", and saying it left him feeling "disgusted."

"I thought Rihanna was frickin horrible," Goldberg said on his CarCast podcast with Matt "The Motorator" D'Andria. "I was disgusted by it. That's all. Let's just say that. I thought it was horrible."

D'Andria said he thought Rihanna's performance was "kind of boring," and Goldberg agreed, calling Matt's comment "the understatement of the year."

Goldberg seems to have an issue with RiRi's crotch grab -- he wasn't the only one -- and felt like the "Bitch Better Have My Money" artist made the performance too much about herself.

In fact, Rihanna chose to do her 13-minute Super Bowl without surprising guests like other artists have done in the past.

Rihanna's SB halftime show at State Farm Stadium in Glendale, AZ was her first time performing in over 6 years... but we now know that he was not alone there.

However, Goldberg is a fan of Chris Stapleton, who sang the national anthem before the Chiefs-Eagles game, praising the singer for doing his job "completely."

118.7 million people watched Rihanna's halftime concert — even more people than actually watched the football game — but we now know that at least one million of those people weren't a fan of the performance.
